MACHINE FOR INSERTING RIBBON INTO LACE.-

SPECIFICATION forming part of Letters Patent N 0. 776,37 9, dated November 29, 1904.

Application filed May 24, 1904. Serial No. 209,579. (No model.)

To all whom, it incty concern:

Be it known that we, Josnrrr A. BERGERON and LoUIs OHARLETTE, citizens of the United States, residing at the city of VVoonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Inserting Ribbon into Lace, of which the following is a specification. 7 Our invention relates to a machine for inserting automatically into lace or edging a ribbon to ornament the same as a trimming for womens underwear and for other purposes, which work has heretofore been commonly done by hand by means of a tape-needle, bodkin, or other suitable instrument.

With this object in view our invention consists of the novel construction and combination of the several parts hereinafter described, and specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a front elevation of our improved machine for inserting ribbons into laces. Fig. 2 is a plan view of a piece of cloth trimmed with lace .or edging which is provided with openings or holes through which the ribbon is to be inserted. Fig. 3 is a plan view of the same after the ribbon has been so inserted. Fig. 1 is. a perspective View of the needle used in said machine. Fig. 5 is a side elevation of the needle and needle-guides and also shows the ribbon and the'means of securing the same to the needle. Fig. 6 is a view of said machine as seen partly in side elevation and partly in section on line X X of Fig. 1. Figs. 7, 8, 9, 10, and 11 are views partly in section on line X X of Fig. 1, showing the needle, ribbon,

lace, needle-carriers, and rotary cams in their In the drawings, 1. represents the table or bed of the machine. The plate 2 is rectangu lar and is set into a recess of the table or bed, as seen in Fig. 1, and is secured in place by screws 3 or otherwise. A frame4 is connected with the plate 2 or is supported in any suitable manner; It has three bearings 5 5 and 6. On the upper side of the bottom portion of the frame 1 is a standard 7, having a tubular bearing or sleeve 8 on the top thereof. The main or driving shaft 9 is rotatably mounted in the bearing 6 of the frame 4: and in the tubular bearing 8 of the standard 7. Adriving-pulleylO, having a hub 11, is secured by a set-screw 12 upon theshaft 9 and is rotated by a belt 13. A gear 1 1 is mounted on the shaft 9 and held thereon by a set-screw 15, which passes through the hub 16 of said gear.

An eccentric circular disk 17 has a hub 18 and is mounted upon the shaft 9, to which it is fastened by the set-screw 19. r This disk 17 has a peripheral groove.- An eccentric circular disk 20 has a hub 21 and is mounted on the shaft 9, to which it is fastened by the setscrew 22. A cam-shaft 23 is mounted rotatablyin the bearings 5 5 of the frame 4:, above the shaft 9 and parallel'thereto. A gear 24 has a hub 25, by which it is mounted on the shaft 23 and is fastened thereon by the setscrew 26. The gear 24 engages with and is turned by the gear it. On the shaft 23 are two cams 27 and 28. The cam 27 has a hub 29, through which the shaft 23 passes, and a set-screw 30 fastens said cam in position. The cam 28 has a hub 31, through which the shaft 23 passes, and a set-screw 32 fastens said cam 28 in position. These cams 27 and 28 are circular on their peripheries and each has on its inner face a cam-groove, the cam 27 having the cam-groove 33 and the cam 28 having the cam-groove 34.

Arms or needle-carriers 35 and 36 have, respectively, the circular bands or straps 37 38. The band or strap 37 of the needle-carrier 35 is loosely mounted in the peripheralgroove of the eccentric disk 17, and the band or strap 38 of the needle-carrier 36 is loosely mounted in the peripheral groove of the eccentric disk 20. The needle-carrier 35 has a stud 39, on

which is mounted an antifriction-roller 10, and

this roller 40 has a rolling lit in the groove 33 of the cam 27. The needle-carrier 36 has a stud 41, on which is mounted an antifrictionroller 42, and this roller 42 has a rolling fit in the groove 34 of the cam 28. On the top of the needle-carrier 35 is the L-shaped needlehook 43, one end of which is screw-threaded and passes through the needle-carrier 35. Nuts 44 45, engaging the threaded end of the needle-hook 43, allow it to be set in an adjusted position. Similarly a needle-hook 46 is secured on the top of the needle-carrier 36 and is adjusted in position by the nuts 47 48.

A feed 49 is mounted movably beneath a feed-plate 50, which is mounted on the plate 2 and held in position thereon by the screws 51. The feed 49 resembles that of a feed for a sewing-machine and has on its upper surface a series of serrations. This serrated portion of the feed has'vertical and horizontal movements up through and along the slots 52 53 of the feed-plate 50. The feed 49 has an integral plate 54, which is longitudinally SlOlZ, ted, as shown at 55 in Fig. 12, and is supported on the upper end of a T-shaped feed-bar 56 by means of screws 57 57, which pass through the slot 55 of the plate 54 of the feed 49 into said end of the bar 56. The feed mechanism is shown in Figs. 1, 6, and 14. A shaft 58 is loosely mounted in the bearings of two standards 59 59, which extend up from the bottom portion of the frame 4. Two rocker-arms 60 and 61 are mounted on the shaft 58 and are fastened thereon by setscrews 62 63, which pass, respectively, through the hubs 64 65 of said rocker-arms.

On a stud 66, Fig. 14, is mounted a link-bar 67, which has at one end a U-shaped slot, by which said end fits loosely over and upon said stud 66. A cross-pin 68 prevents said end of the link-bar 67 from leaving the stud 66. The opposite end of the link-bar 67 is loosely connected to the outer end of the rocker-arm 61' by the pivot 69. The stud 66 is made fast in and projects from a sliding block 70, which has beveled edges and is movable in a dovetailed groove 71 of a disk 72, which is fastened concentrically on the driving-shaft 9. One side of the disk 72 has a flat surface, and a plate 73 is placed thereon and held in position by the screws 74 74. An adjusting-screw 75 has a head 76 and a collar 77, so that there is left between the head and collar a circumferential groove in which the edges of a slot of the plate 73 extend. By the slot arrangement in the plate 73 the adjusting-screw 75 is prevented from longitudinal movement. The inner end of the adjusting-screw 75, passing through a threaded hole in the sliding block 70, causes said block to move in the groove 71 of the disk 72. The disk 7 2- is mounted on the shaft 9 by a hub 78 and fastened thereon by a set-screw 79.

A circular disk 80 is eccentrically mounted on the driving-shaft 9 and is peripherally grooved, as shown in Figs. 1 and 6. The front end of the horizontal portion of the feed-bar 56 terminates in a U-shaped yoke 81, which embraces the eccentric disk 80 in the peripheral groove thereof. The opposite or rear end of the horizontal portion of the feed-bar 56 is loosely connected to the outer end of the rocker-arm 60 by the pivot 82.

The needle-head of the machine is shown at 83 and is in the form of a bracket having an upwardly extending portion and a downwardly-extending portion. In the upper portion of this head is a circular bore, in which is loosely mounted the stem 84 of the presserfoot 85. A spiral spring86 surrounds the stem 84 and has its upper end bear against the under side of said head portion and its lower end bear against the upper surface of the presser-foot 85. The upper end of the needle-carrier 35 passes up through a slot 87 in the plate 2, as seen in Figs. 12 and 13. A needle-guide 88 extends vertically between the upper and lower portions of the head 83 and is fastened thereto by the screws 89 89. As seen in Figs. 1 and 5, said guide has two opposite longitudinal vertical grooves, which are the ways in which the needle moves up and down.

The needle is shown separately at 90 in Fig. 4. It has two rounded ends and is of a suitable thickness to slide easily up and down the grooves of the needle-guide 88. Near each end of the needle 90 is a circular opening 91. There is also a slot 92 from one side thereof,

located midway of the needle ends and opening into a central aperture 93. A needletongue 94 in a slot of the needle (indicated by dotted lines in Fig. 5) is mounted at one end upon a pivot 95. The ribbon 96 from a spool (not shown) passes through the central aperture 93 of the needle 90 (having been easily introduced therein by passing it through the slot 92) and is engaged by said needle-tongue 94, which when extended, as indicated by dotted lines in Fig. 5, is secured in place by the swinging of the point of the needle-tongue 94 into said needle-slot.

The lace or edging which is to be ornamented by the insertion of ribbon by means of this improved machine is designated as 97 and is shown in Figs. 2 and 3 as stitched to the edge of a fabric or garment 98. The lace or edging has equispaced holes 99, separated from each other by cross-threads 100 or otherwise,

formed in the pattern or design.

Having thus described the parts of said improved machine, we will now proceed to explain its operation.

By means of the screw 75 the sliding block 70 is moved along the slot or groove 71 of the disk 72, Fig. 14, and by the degree of eccentricity so given to the stud 66 as related to the main shaft 9 the length of the feed 49 in a horizontal direction is secured, so that said feed will move a distance equal to the distance of the holes 99 of the lace o edging 97 apart. Thus as the driving-shaft 9 rotates it carries with it the disk 72, and by reason of said eccentric positioning of the stud 66 a reciprocating movement is given to the linkbar 67 and communicated thereby to the rocker-arm 61. The rocker-arm 61 being fast upon the shaft 58 oscillates the same, and as the rocker-arm is also fast upon the shaft 58 the rocker-arm 6O imparts areciproeating movement to the feed-bar 56, to which it is pivotally connected at 82. This reciprocating movement of the feed-bar 56 gives a corresponding movement to the feed 49, which is mounted adjustably thereon by the screws 57 in the slot 55 of the plate 54: thereof. At the same time the rotation of the driving-shaft 9 gives motion to the eccentric disk 80, mounted thereon, and so a reciprocating vertical movement is imparted by the eccentric disk to the feed-bar 56 by the yoke 81 thereof, which embraces the disk 80 in the peripheral groove thereof. This gives the requisite vertical movement to the feed 49. The spring 86, surrounding the stem 84 of the presser-foot 85, keeps the presser-foot normally depressed to engage the upper surface of the fabric which is fed by this mechanism. The lace 0r edging 97 is placed upon the feed-plate 5O beneath the presser-foot 85 and upon the serrated surfaces of the feed 49, which extend up through the slots 52 53 of the presser-foot plate, and by the operation of the feed mechanism just described is fed periodically to bring successively the holes 99 of said lace or edging 97 into position to allow the passage of the needle therethrough. The ribbon is secured to the needle 90, as already explained, and as the machine operates and brings the holes or openings 99 of the lace or edging in proper relation to the needle 90 said needle carries the ribbon down through the hole 99 then in position, and afterward when the lace or edging 97 has been fed forward one space said needle carries the ribbon up through the next hole 99, and so on.

The movements of the needle 90 are as follows: Beginning with the needle 90 in its highest position, the needle-hook 43, it will be understood, has been properly adjusted to enable it to engage the upper opening 91 of the needle 90. The needle-carrier 35, being at its most elevated position, is moved by the engagement of its roller 40 in the cam-groove 33 of the cam 27 as said cam 27 turnswith the shaft 23, (the latter being rotated by the gear 2 L thereon, which is driven by the gear 14 of the main or driving shaft 9,) so that said hook 43 enters the upper opening 91 of the needle 90. The continued rotation of the cam 27 causes the needle-carrier 35 to descend, and so the needle 90 by reason of its engagement with the needle-hook 4:3 is moved down the grooves of the needle-guide 88, wherein said needle 90 is mounted slidably. In this manner the needle 90 is passed down through the hole 99 of the lace 97 then in position to receive it, and the ribbon 96 is carried with'the needle 90 through said hole.

hen the needle-carrier 35 by its hook 43 has moved the needle 90 to the lowest limit of its vertical travel, the carrier 35 is withdrawn by reason of the roller 40 thereof coming into that part of the groove 33 of the cam 27 which is shaped to effect such movement, and thus the needle-hook 43 is drawn out of the upper opening 91 of the needle 90; but at that time the needle-carrier 36, by reason of the engagement of its roller 42 in the groove 34: of the cam 28, moves toward the needle 90 and causes its needle-hook 46 to enter and engage the lower opening 91 of the needle 90 and to move said needle 90 up along the ways of the needleguide 88 to the position first described, and then the needle-carrier 36 is withdrawn by the cam 28 from the needle 90 and causes its need 1 ehook 16 to disengage from the needle 90, the lace 97 being moved forward one space by the feed mechanism at the end of each operative movement of the needle-carriers 35 36. Thus the operation continues successively until the ribbon 96 is drawn into all the holes 99 of the lace 97 scrim/ion.
